A processing solution container is provided which can contain two or more fluids separately. The container includes an expandable housing for receiving processing solution therein having a port for charging and discharging the solution, and a partition in the housing for dividing the interior of the housing into a plurality of compartments, but allowing fluid communication between the compartments when the housing is expanded.

In an apparatus for processing a photosensitive sheet by passing it through processing solution in a tank, vertically spaced-apart roller units are disposed in the tank for normally feeding the sheet downward and then upward at opposite sides thereof, but capable of reversing the sheet when selected. The sheet is turned around a selected roller unit whereby the length of the path that the sheet travels through the solution and hence, the duration of processing time is variable.

A window grating arrangement is placed across a window opening in a building wall to keep out burglars but can be removed from the window opening alongside the wall in a required time, especially so as to enable dwellers to flee in an emergency. The window grating arrangement is so constructed that a pair of parallel stationary supports are fixed on the surrounding portions of the window opening in the wall while a mobile assembly of protective bars are sustained slidably on the supports.

An apparatus for processing a web or sheet of photosensitive material by passing it through a processing tank is provided. The apparatus includes a processing tank of the closed type having an inlet slit and an outlet slit for the photosensitive sheet. The tank is filled with processing solution and replenished with solution from an external supply. Each of the inlet and outlet slits has such a small opening that the processing solution may not leak through the slit due to its surface tension. The photosensitive sheet is carried into the tank via the inlet, through the tank along a predetermined path, and then out of the tank via the outlet by means of rollers or other conveyors.

A low inertia, speed variable induction motor comprises a frame, a stator fixedly placed in the frame, a yoke fixedly placed in the frame in opposition to the stator with a predetermined gap and a cup-shaped rotor which is inserted into the gap and is fixedly mounted on an output shaft supported in the frame in a freely rotatable manner. Rotating magnetic field is produced in the gap by the stator and the yoke to generate a rotational torque of the cup-shaped rotor. The cup-shaped rotor is formed of a material or materials having a hysteresis characteristic and an eddy current producing characteristic to obtain a large torque.

This invention relates to sewing machine drive devices, and more particularly to a sewing machine drive device which, in order to stop the sewing needle at a desired position, drives the sewing machine at an ultra low speed and changes the speed of the sewing machine to a desired value immediately before the needle is stopped. The device comprising a sewing machine drive mechanism having an induction motor (14) and a braking unit (18), and a position detector (24) coupled to the output side of the induction motor, for detecting a sewing needle's position, the induction motor being subjected to variable speed driving by a motor speed control circuit (32) including an inverter circuit, and the braking unit (18) being operated with the aid of a detection signal from the position detector (24).
